Biological Activity

KH-4-43, an inhibitor of the E3 CRL4 ligase complex, demonstrates anticancer activity by targeting the core of the E3 CRL4. It exhibits a binding affinity (Kd) of 83 nM to the E3 ROC1-CUL4A CTD and 9.4 uM to the closely related ROC1-CUL1 CTD (1).

Safety & Regulatory

For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.

Can high-temperature sterilization be used for inhibitors?

Most small molecule inhibitors are not compatible with autoclaving (121 °C), which can cause thermal decomposition or loss of biological activity. For sterile cell-based experiments, filter-sterilize working solutions through a 0.2 µm membrane after dilution into aqueous buffer. Verify thermal stability in the DataSheet before applying any heat treatment.

How to store the inhibitor solutions?

After the stock solution is prepared, it is typically stored at -80°C and can be kept for over 1 year. It is recommended to aliquot to avoid repeated freeze-thaw cycles. For frequent use, it can be stored at 4°C for over a week.

Need this compound in a format that drops straight into your assay? We can tailor formulation, chemistry, and documentation so your results stay consistent across runs and re-orders.

  • Format options: solid or pre-dissolved solution (choose solvent), target concentration, aliquots, light/moisture-protected packaging
  • Chemistry options: free base/acid vs salt forms, hydrate/solvate preference, stereoisomer control (single enantiomer or racemate), close analogs
  • Add-on labels & handles: D/¹³C/¹⁵N isotopes (LC-MS/internal standards), azide/alkyne or other functional handles for conjugation
  • QC & documentation: standard COA or enhanced analytical pack (HPLC/LC-MS/NMR), chiral purity, residual solvents, water content (KF), method-specific specs
  • Scale & continuity: mg to gram scale, bulk pricing, lot reservation, repeat-order continuity

To quote quickly, tell us: compound name + CAS/structure (SMILES or mol file), intended assay context, solvent preference, salt/stereochemistry requirements, purity/QC level, and the amount (mg–g).
